Description

Self-conveying apparatus for lubricating bearing
The present invention relates to a kind of self-conveying apparatus that is used for bearing lubrication, this device has a filler opening, an oil export and a side conduit pump that has preferably flat conveying blade.
For the bearing to machinery is lubricated, many kinds system inequality is arranged.The method of low pressure oil circulating lubrication is often adopted in the bearing lubrication of big machinery.When adopting this method, oil is extracted out from oil groove by a pump, middle by cooling unit and filtrating equipment (or a cooler-filter unit), send into high-level container then.Oil from this container by gravity flow to the bearing that will lubricate.This lubricating system efficient is very high, and also very economical because circuit oil is conducted through a filtrating equipment, thereby can be used within a certain period of time repeatedly.
However, there are many defectives in this system, and special on important equipment, it is very serious that these defectives are proved to be.
On the visual plant that adopts said system, be typically provided with two oil pumps, when a pump quits work, can use another pump instead.For further improving Security, each pump can be respectively by different mains supplies.Generally speaking, a pump three-phase alternating-current motor, another pump then uses direct current motor, and direct current is taken from the emergency electric system that storage battery is supplied with mostly.So naturally just have that two power supply systems all break down or two motor or two danger that pump all breaks down at short notice.Under these situations, in any case the machinery that will lubricate all must be shut down.Even press the high-level container of corresponding optimum design, oil supplying device also only can be worked time (being about 5 to 10 minutes usually) of one section weak point again.
Another shortcoming is, needs lubricated machinery at first will make high-level container be full of oil before starting.In some bearing means,, also can delay starting of machinery because of bearing is not used oily filling in advance.
High-level container not only is higher than the machinery that will lubricate, and usually is arranged on one mechanically in another space of face.In practice, because desired position is inconsistent with in fact operational position, usually cause trouble.Three pipelines (oil inlet pipe, oil outlet tube and spill pipe) that lead to high-level container often also are weak links, their not only often account for valuable position and zones that is difficult to sometimes be arranged to avoid the dead angle and avoids heating.
Therefore, task of the present invention be to provide a kind of be used for machinery, especially for big machinery, can avoid above-mentioned defective and work and very economic bearing lubrication system simultaneously fool proofly.
This task is solved by the present invention.It is characterized in that, side conduit pump be arranged on bearings mounted the same axis on, preferably nestle up bearing setting; And each conveying blade has one with duplicate and corresponding with it groove of side conduit cross section on the same high height of side conduit.
The advantage of Chan Shenging is therefrom, and bearing lubrication and accessory power supply are uncorrelated, thereby running is very reliable and economical.To bringing into operation and the continuous working period of the oil supplying device of the bearing fuel feeding that will lubricate, under any circumstance all with running shaft to begin rotation consistent with lasting rotational time.
In addition, the oil that is transferred of making spiralling in the conduit of side can not interrupt, thereby has guaranteed the greasing free of discontinuities, and this also is one of advantage.
Another advantage is, because oil feed line is very short, cooling water can be discovered out if enter the oil feed line system very soon.
In a kind of structure of the present invention, the side conduit is arranged in the part area of the total circumference of side conduit pump.Such structure is favourable, because by the length of side conduit correspondingly is set, oil pressure can meet the requirement of corresponding running exactly, the rotational speed of side conduit pump upward remains unchanged owing to this pump is placed in axle.
A kind of special development of the present invention is that the length of side conduit (7) can change by changing the arciform liner spare of removable annulus.
Just can in operating conditions has the machine of acute variation frequently, oil pressure be adjusted to thus to meet the requirement of corresponding operating condition and need not to change side conduit pump.
Another being characterised in that of the present invention, oil-way system are conducted through a cooler and a filter, or by a cooler-filter unit.
Oil is filtered accordingly and cools off, further improved the running margin of safety, this has just guaranteed the cooling to bearing.Also further improved the Economy of system of the present invention by this way.
The present invention will be described in detail by an embodiment.Accompanying drawing illustrates a collar receiver on a bearing that will lubricate with sectional view, and affiliated side conduit pump.
Be bearing radial force and axial force, the axle head (2) of axle (1) is provided with the axle collar (3) that the sliding bearing that is combined (4) closes.
Upward locate to be provided with side conduit pump (5) at this axle head (2), special conveying blade (20) is housed on its running wheel (6) near combination journal bearing (4).Side conduit (7) is designed to semicircular cross section.Conveying blade (20) on same high height, be provided with side conduit (7) one semicircular, with the duplicate and corresponding groove of side conduit cross section (21) with it.
For prevent oil from the side conduit pump (5) spill and avoid impurity to enter in it, be provided with two seal rings (8,9).Be provided with filler opening (10) in the bottom of side conduit (7), be provided with oil export (11) at an upper portion thereof.Side conduit pump tightens on combination journal bearing (4) by a supporting ring (12).Combination journal bearing (4) and side conduit pump (5) are closed by the support (14,15) of the support housing (13) of two-piece type.The oil circuit (16) that leads to the sections (22) of combination journal bearing (4) is connected with the oil export (11) of side conduit pump (5) by a pressure oil pipe (17).The groove that two splashproof oil rings (18,19) are contained in respectively on each axle head (2) is interior to stop from the next leakage of oil of combination journal bearing (4).
Start preceding combination journal bearing (4) in the first time and must pour into oil, make oil level roughly be in the external diameter of axle (1) on the position intermediate of side conduit (7) lower end.Oil between blade and shell body wall, when impeller (6) rotates, outwards carried with centrifugal force by radially upright conveying blade (20) on the one hand, be squeezed into again in the conduit of side on the other hand, thereby the suction chamber of conduit pump (5) is transported to pressure chamber from the side.By oil from the side the rotating part of conduit pump (5) transfer in the side conduit (7), or conduit (7) is transferred to rotating part from the side, all has pressure to form.The oil that is transferred is made spiralling in side conduit (7).The oil oil export (11) of the upper end of conduit (7) from the side flows out, and flows into the oil circuit (16) of combination journal bearing (4) by pressure oil pipe (17).Oil circuit (16) terminates at the raceway place of combination journal bearing (4), thereby and oil is directly guided on the slip surface of combination journal bearing (4).
By oil is thrown away from conveying blade (20), round in the present embodiment as the part of axle head (2), running wheel (6) dress impeller shaft thereon, and locate to produce a negative pressure at filler opening (10), its makes oil flow out (nachstroemen) subsequently from a unshowned fuel sucking pipe that is connected with a cooler or filter or cooler-filter unit on figure.The length of side conduit correspondingly is set, makes it to account for 270 ° of such confidence bands of total circumference of side conduit pump (5), just can obtain oil lubrication system regulation corresponding to the best of the kinds of bearings that is adopted.When adopting cooler or cooler-filter unit, except lubricated, also additionally bearing is cooled off.
